Thanks for following up with the Community, wayne72.

The steps provided by JonpriL are for QuickBooks Desktop. If you're using QuickBooks Online, you can create an expense and link it with your purchase order. While creating it, you'll be able to manually enter a partial quantity as received.

Here's how:
 

1. In the left navigation bar, use your + New button.
2. Under VENDORS, click Expense.
3. From the Payee drop-down list, choose a vendor.
4. In your Add to Expense section, find the purchase order you're working with and hit its Add option.
5. Enter an appropriate partial quantity received amount in your QTY field.
6. Select Save and close.
   

Now, your purchase order will show a partial quantity received in its RECEIVED column.

When you're prepared to enter that you've received the rest of your units, you can create an expense again and enter the rest that you've received.

Afterwards, your purchase order will show that all units have been received.

You'll also be able to find many detailed resources about using QuickBooks in our help article archives.
